I replaced “just one more prompt” with one 15-minute reset — and my AI bill dropped

For months I had the same pattern:

• work all day
• get tired at night
• spam “one more run” in Claude/Codex/Cursor
• wake up with a bigger bill and no real progress

I thought the problem was model choice.
It was mostly attention quality.

So I started a 15-minute nightly reset:

1. Write tomorrow’s top 3 tasks before opening any AI tool.
2. Put hard spend caps per session.
3. Kill unfinished branches that are just retry loops.
4. Block algorithmic feeds before deep work blocks.

After one week, two things changed:

• my AI spend dropped because I stopped rerunning noisy prompts
• I shipped more because I stopped context-switch doomscrolling

I built two tiny Mac tools for this exact workflow:

• TokenBar — $5 menu bar tracker so I can see token/cost drift in real time (tokenbar.site)
• Monk Mode — $15 feed-level blocker so I can keep useful apps but remove infinite feeds (mac.monk-mode.lifestyle)

No hype: the best optimization wasn’t a smarter model.
It was a calmer system.

If your bill feels random lately, try the 15-minute reset for 7 days and track what changes.
